Jaco,
How are your boxes locking up, I have nfs in use every day, does rpc die?
what kernel are you using? and are you transfering linux to linux, or to some other platform.
The only time I had problems was when my client locked up because I disconnected the server, and it hung the client, the only solution (based on the way I connected), was to reboot. To make matters worse, I rean a script that used du every day, and so there were 12+ instances of du, all trying to run about.
I would suggest using a program like sysstat, or sar, to help you analyse the issues at hand.
